If the output neutral is independently derived through the center tap of the output transformer, the Current on the output neutral would not show up on the input neutral. It would only show up as a load on the 240V.If I understand the test correctly, I need to hook up incoming AC power, but have batteries and solar off, and then a single 120V load connected? Then you want to see what the current is on the incoming neutral?
How could I not have current on the neutral with a single output? Are you saying that the inverter might actually be using the incoming ground as the output neutral because they are internally bonded? [and it's expecting that it's the source of all downstream power, so a bonded ground and neutral is no problem?]
In this test, do you want both incoming hots, the ground, and the neutral all connected?
Yes
